Where exactly do I enter the code?
Only in the EvilFox VPN → Cabinet app section. Not in the website dashboard, not on “Top up balance”, not in tickets.
Do I need a website account?
For oplata.info → EvilFox activation — no. Website registration is for buying configs via site balance (a different flow).
Code rejected — what to check?
1) Full code, no extra spaces. 2) Code not already used. 3) Payment succeeded and code was issued. 4) Latest EvilFox version. 5) Internet during activation.
Can I use one code on several PCs?
Usually one activation / device limit per product terms. Reusing on another PC may fail if the code is already redeemed.
How is this different from a site balance code?
EvilFox code (oplata.info) — subscription in the app. Balance / Digiseller on balance.php — credits RUB to the website account for 3x-ui / Remnawave / Amnezia in the site cabinet.
Paid but no code
Check the success page and email (including Spam). Digiseller/oplata.info purchase history usually shows the code again. If missing — contact support with order id / payment time.
Activated but VPN does not work
Confirm the subscription is active in the app cabinet, a server is selected, and the connection is on. Try another protocol/server if the ISP blocks. If the app shows an active sub but sites look “local”, enable full tunnel / Kill Switch.
